I am an Associate Professor in the Department of Anthropology at the University of Wisconsin-Madison, United States. I also hold a Senior Honorary Research Fellow position in the School of Physiology at the University of the Witwatersrand, South Africa, and affiliate faculty positions in the Department of Integrative Biology and the Center for African Studies at UW-Madison. My research aims to investigate individual, population and species differences in behavioral adaptation and physiological competence, particularly in relation to the consequences of social and climatic challenges. I am director of the Swebeswebe Primate Research Project (South Africa), where I study the behavioral ecology and environmental physiology of wild chacma baboons and vervet monkeys. I also take both an experimental and mechanistic modeling approach to the study of primate thermoregulation, examining the role that local climate plays in shaping the behavioral and physiological adaptations of living primates, and those of our primate and hominin ancestors. I welcome enquiries from prospective graduate students and all those interested in gaining field experience.
